United States Patent O 3,456,390 DOOR GASKET Adrian F. Hulverson, Grosse Pointe Woods, `lohn W. Harper, Detroit, and Floyd G. Saxton, St. Clair Shores, Mich., assignors to Fruehauf Corporation, a corporation of Michigan Filed Jan. 9, 1967, Ser. No. 607,994 Int. Cl. E06b 7/23 U.S. Cl. 49-489 8 Claims ABSTRACT F THE DISCLOSURE A seal is provided within the channel of a door jamb t0 which the door is hinged which engages and seals the inner face of the door and the door edge. The seal is mounted on one wall of the channel with a pair of converging arms extending toward the other wall in position to seal the door face and the adjacent edge when the door is closed. An extension on one of the arms provides a seal with an inner surface of the channel wall.

SUMMARY OF THE INVENTION The present seal is adaptable for sealing the edge of the door adjacent to the hinge on which it is swung to open and closed position. The seal is of U-shape having a base from which a pair of converging webs extend, one of which defiects into sealing engagement with the face of the door as .the other web engages and seals the edge of the door. With such a seal, the edge of the door and the face disposed 90 therefrom are sealed against the passage of water thereabout. Should any water be forced by the seal at .the edge of the door, this water will be prevented from passing beyond the door by the seal engaging the adjacent face thereof. It is within the purview of the invention to add a third web at the base of the seal which engages the jamb of the door to provide a further seal against the passage of water to the base of the seal. A similar seal can be provided for the jamb by adding a bead to the end of the web which engages the door edge to have the bead move into engagement with the jamb when the web is engaged by the door edge. In any of the arrangements, a positive seal is provided for the edge and face of the door and with the jamb associated therewith which provides positive assurance that no water can enter between the door and jamb into the interior of the body.

BRIEF DESCRIPTION OF THE DRAWINGS FIGURE 1 is an end view of a trailer having a pair of doors hinged to the side jambs thereof;

FIGURE 2 is an enlarged broken sectional View of the structure illustrated in FIGURE 1, taken on the line 2-2 thereof;

FIGURE 3 is a broken, enlarged view of the structure of FIGURE 2, as viewed within the oval 3 thereof;

FIGURE 4 is a view of the elastomeric sealing element illustrated in FIGURE 3, and

FIGURE 5 is a view of structure, similar to that illustrated in FIGURE 3, showing another form which the sealing element may assume.

Referring to FIGURES l to 4, a rear end frame of a trailer or like structure, having a pair of doors 11 and 12 pivoted thereto, is secured to the side walls in a suitable manner herein illustrated as by rivets 14. The outer part of the frame has a channel 16 and hinge wings 17 welded or otherwise secured thereto. The spaced arms 18 of the wings 17 have wing sections 19 secured thereto by pivot pins 20. The wings are secured to the doors 11 and 12, the edge 21 of which enters the channel 16 when the door is in closed position.

ICC

For positively sealing the door in the channel 16, a sealing strip 22 is secured to the wall 23 by a channel strip 24 having reversely bent ends 25 which is welded or otherwise secured to the wall. The seal is made of elastomeric material having a web 26 which is reduced in thickness at 27 to provide greater flexibility thereto. An arm 28 extends outwar-dly from the web 26 having a tapered end 29 that is directed inwardly. A spaced outwardlyLdirect-ed arm 31 extends from the web 26 having a tapered end 32 which extends inwardly toward the tapered end 29. The arm 31 has a tapered web 33 which extends outwardlysubstantially at right angles to the tapered end 32.

As seen from FIG. 3, when the door 12 is in closed position, the inner face 34 is engaged by the arched p0rtion of the tapered end 29 with the end extending outwardlytoward Vthe door end 21. As the door end 21 moves further into the channel 16, the tapered end 32 is deflected toward the bottom of the channel and retained in firm sealed engagement with the door end. The tapered web 33 engages the inner bottom wall 36 of the channel 16 to prevent any water from passing rearwardly to the channel supporting strip 24. With this arrangement, the tapered end 32 seals the end of the door, the tapered end 29 seals the inner face 34 0f the door, while the tapered web 33 seals the bottom wall 36 of the channel 16 against the passage of water to and beyond the channel supporting element 24. It will be noted that strong supporting arms 28 and 31 extend from the web 26 from which the extending ends 29 and 32 and the web 33 are deflected to seal the door and the bottom wall of the channel against the passage of water into the trailers body.

In FIG. 5, a seal 40 is illustrated having the web 26 and arms 28 and 31 extending outwardly therefrom. The arm 28 has an extending end 29 thereon while the arm 31 has a tapered web 41 in extension thereof. The extending end 29 and tapered web 41 engage the face 34 and the end 21 0f the door 12, respectively. Instead of employing the extending web 33 to seal the inner wall 36, the web 41 -has a cylindrical bead 42 on the end so located that when the rear edge 21 of the door engages the tapered web 41, the bead 42 will engage the side wall 43 of the channel 16 and thereby provide a seal to prevent water from passing across the inner wall of the channel. In either arrangement, the inner face and edge of the door, as well as the space between the door and the inner wall of the channel is sealed against the passage of Water by the seal of the present invention.

What is claimed is:

1. In combination with a seal, a door and a channelshaped jamb having a web and side walls to which the door is pivoted, a seal made of elastomeric material and of U-shape having a web and two extending arms, means securing said web to a jamb side wall, said two arms extending toward the other jamb side wall in position to have one arm engage the inner face of the door and have the other arm engage the adjacent edge of the door and said other wall of the jamb when the door is closed to provide a double seal for the door against the ingress of water when in closed position.

2. The combination as recited in claim 1, wherein a web provided on one of the extending arms engages the bottom wall of the channel shaped jamb for sealing said bottom wall against the ingress of water.

3. The combination as recited in claim 1, wherein the door extends into the channel of the jamb, and an extending web on said seal which engages the bottom wall of the channel shaped jamb.

4. The combination as recited in claim 1, wherein the arms of said seal are tapered to form thin ends which are dellected in the same direction when engaged by the 3 inner face and an adjacent edge of the door when the door is in closed position.

5. The combination as recited in claim 4, wherein one of the extending ends of the arms has a bead thereon which engages said other jamb wall when the door is closed.

6. 'Ihe combination as recited in claim 4, wherein one of the arms has a tapered extending web which engages the bottom wall of the jamb channel.

7. In a seal for a door as recited in claim 6, wherein the extending web is disposed in substantially right angle relation to the extending end of the arm.

8. The combination as recited in claim 1, wherein the two extending arms have the ends tapered and converged toward each other so as to readily deect when engaged 15 by the inner face and edge of the door.
